Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a removable auxiliary ballast device for underwater vehicles.

[0002]

[Prior Art]

 For example, as an underwater sightseeing boat, conventionally, as shown in the longitudinal sectional view of FIG. 4, in addition to the front ballast tank 02, the central ballast tank 03, and the rear ballast tank 04, which are respectively arranged inside the pressure shell 01, It is known that the portable lead ballast 05 is arranged in the personnel space 06 inside the pressure-resistant shell 01 in consideration of maintaining the balance of the hull against waves when the center of gravity is high or when the ship is floating.

However, such a ship has the following drawbacks. (1) Since the ballast tanks 02, 03, 04 and the portable lead ballast 05 are arranged or arranged in the pressure-resistant shell 01, increasing the capacity of them will lead to an increase in the size of the ship, Therefore, there is an economic problem. (2) Since the portable lead ballast 05 is loaded and unloaded by the crew from the lifting cylinder 07, the weight is limited, and the number is large, and there is a risk of falling and injuring when loading and unloading. There are problems in labor saving and safety.

[Problems to be solved by the device]

 The present invention has been proposed in view of such circumstances, and provides an attachable / detachable auxiliary ballast device for an underwater vessel which is easy to handle without increasing the size of the hull, and is therefore economical, labor-saving and safe. The purpose is to do.

[0005]

[Means for Solving the Problems]

 To this end, the present invention comprises racks which are laid one by one in front and rear directions along the central port of the pressure shell and extend in the vertical direction, and an elevator which meshes with each of the racks via pinions. A solid ballast storage container whose front and rear portions are supported by the elevators, respectively, and a plurality of horizontal partition plates for positioning solid ballasts which are provided inside the solid ballast storage container at appropriate intervals in the front-rear direction. It is characterized by

[0006]

[Action]

 According to such a configuration, the following actions are performed. (1) A rack that is attached to each of the center and left and right sides of the pressure-resistant shell at front and rear at appropriate intervals and extends in the vertical direction; and an elevator that meshes with each of the above racks via a pinion. Since the solid ballast storage container supported by each of the above elevators is installed, the auxiliary ballast device can be installed outside of the pressure shell, thus avoiding an increase in the size of the underwater vessel and improving economic efficiency. In addition, the solid ballast can be mechanically attached to the lower part of the underwater vessel. (2) Since a plurality of horizontal partition plates for positioning the solid ballast are provided inside the solid ballast containment vessel that project at appropriate intervals in the front-rear direction, the positions of the water and the center of gravity of the submersible can be set freely. can do.

【Example】

 An embodiment in which the present invention is applied to an underwater sightseeing boat will be described with reference to the drawings. The same reference numerals as those in FIG. 4 denote the same members as those in the same drawing, respectively, and FIG. In FIG. 1, reference numeral 1 denotes a rack extending in the vertical direction, which is laid one by one on the left and right sides of the central portion of the pressure-resistant shell 01 at front and rear, and 2 can move up and down along the rack 1 via a motor-driven pinion 3. The elevators 4 and 4 are stoppers with limit switches provided at the lower ends of the racks 1, respectively. Reference numeral 5 is a lead ballast storage container that extends horizontally in the front-rear direction and has both ends supported by the elevator 2, and its shape is a vertically split horizontal cylindrical shape that can be opened and closed by a hinge 6 and locked by a fastener 7 in a closed state. In addition, the inside is divided into a plurality of sections at equal intervals in the front-rear direction by a semicircular lateral partition plate 8 in the left-right direction. Reference numeral 9 is a short cylindrical lead ballast that can be carried in and out of the compartment of the lead ballast storage container 5, and 10 is a viewing window.

In such a device, in order to add the lead ballast 9 to the lower position of the underwater sightseeing boat, in FIG. 1, with the underwater sightseeing boat floating, the fastener 7 is unlocked and the lead ballast storage container is released. 5 is opened, and lead ballasts 9 are arranged in predetermined partitioning compartments according to the desired drinking water and position of the center of gravity. The lead ballast storage container 5 is closed and the fastener 7 is locked. Next, when the elevators 2 and 2 are simultaneously driven using the operation panel in the ship, the pinion 3 of the elevator 2 descends along the rack 1, and when it comes in contact with the stopper 4, the elevator 2 stops and the lead ballast storage container 5 Is installed at the position indicated by the chain line. In addition, in order to remove the lead ballast 9 from the underwater sightseeing ship, the above procedure is reversed.

According to the apparatus of this embodiment, the following effects can be obtained. (1) A rack that is attached to each of the center and left and right sides of the pressure-resistant shell at front and rear at appropriate intervals and extends in the vertical direction; and an elevator that meshes with each of the above racks via a pinion. Since the lead ballast storage container supported by each of the above elevators is installed, the auxiliary ballast device can be installed outside of the above pressure-resistant shell, avoiding an increase in the size of the underwater sightseeing boat and improving economic efficiency. Can be increased. Further, the lead ballast can be mechanically attached to the lower part of the underwater sightseeing boat, so that the stability of the underwater sightseeing boat and the labor saving and safety of the ballast work are improved. (2) Since the lead ballast positioning containers are provided with a plurality of lateral partition plates for positioning the lead ballasts that project at appropriate intervals in the front-rear direction inside the above-mentioned lead ballast containment vessel, it is possible to freely position the diving water and the center of gravity of the underwater sightseeing boat. Can be set, thus improving the stability of the underwater sightseeing boat.
